CARBURETER. I

Specification of Letters Patent.

Patented Sept. "2, 1915.

Application filed October 28, 1914. Serial No. 868,922.

useful Improvements in Garbureters, of'

which the following is a specification.

This invention relates to a carbureter espeeially constructed for volatilizing lowgrade hydrocarbon fuels and mixing same with air to produce a gas suitable for household uses, such as lighting and cooking.

One of the objects of the invention is to provide a simple, cheaply manufactured, easily operated carb ureter which is compact in construction and automatic in operation and which is provided with means for automatically admitting air and gasolene to the carbureting chamber in measured quantities.

Another object of the invention is to provide an auxiliary vaporizing attachment, by means of which the fuel be further volatilized and a perfect mixture secured. Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a side elevation of the carbureter and gasometer, with connected operating mechanism. Fig. 2 is a vertical central section of the carburetor. Fig. 3 is a perspective of one of the fiber cartridges mounted in the carbureting tube. Fig. 4 is a cross section on line M, Fig. 5, with fiber in place. Fig. 5 is a side elevation of the fiber cartridge frame employed in the auxiliary vaporizer.

Moreparticularly described, A. indicates the carbureter proper, B a receiver or gasometer connected with same, and Gthe coils of an auxiliary vaporizer hereinafter to be more fully described. The carburetor proper consists of adouble walled tank A, in the annular space of which is vertically mov-.

: link 7, is a bucket 8. This bucket is pivoted off center, as at 9, so that it will normally assume the tilted position shown in Fig. 2, which position is limited by a set-screw 10. The inner tank may be filled with gasolene, as indicated at 11, through a screw plug opening 12 formedin the bell or by means of a floating valve or any other suitable connection. The quantityof gasolene contained or elevated by the bucket, when the bell movesin an upward direction, is regulated by the tilted position of same or the ad-. justment of set-screw 10.

Secured inside of the inner tank and mounted eccentrically with relation to cylinder 3 is a second cylinder 13 which will hereinafter be termed the carbureting tube. This tube is provided with an inclined extension tube 14 through which the gasolene, elevated by bucket 8, is'delivered to the carbureting tube proper. The carbureting tube is open at its upper end and communication therewith is also formed through the filling tube 14.

Mounted interiorly of the tube below the filling opening is a plurality of fiber can tridges'15 which are stacked one upon the other. These cartridges are more particu larly shown in Fig. 3 and consist of a wire screen ring 16 over which is wound, lengthwise and crosswise, a cotton or hemp string, such as is indicated at 17. This in a manner forms a coarse fabric onboth sides of the ring through which the gasolene admitted through tube 14- is permitted to pass. A portion of the gasolene poured in through the filling tube becomes absorbed bythe fiber strings of the several cartridges as a great number of same are stacked one upon the other throughout the length of the tube.

The piston 4;, with connected bell 2, is preferably lifted by water under pressure entering through a pipe 18 connected with a suitable sourceof supply. The water admitted through pipe 18 to lift piston 4 is controlled by apair of'valves 19 and 20; valve 19 being the inlet valve and valve 20 being the exhaust or outlet valve. These valves are automatically opened and closed, as the case may be, by a tappet head 21, pivotally mounted, as at 22, upon a standard 23. This in turnis operated by a cross-arm or tube2e which is connected by a chain 25 with an arm 26 secured to the bell on one i to the extreme lower position, cable 27'will side and by a cable 27 passing over a pulley 28 on the other side.

In operation, when the bell moves down be pulled in the direction of arrow at. and will consequently tilt tube 24, with connected tappet head21about pivot 22. This will bring shoulder 29 ofthe tappet head in engagement with a lever 30 on-the exhaust valve and will depress this or move it into theclosedpgosition; The lower shoulder 31 on thetappet head will at the same-time upward position chain 25 will reverse the movement ofthe tappet' head, causing'this to close-valve 19 andopen exhaust valve 20.

The water previously admitted to the cylin der is thus permitted'to esca-peand bell2, with connected rod' and piston, will consequentlybepermitted to drop down and expel the air previously admitted. The air passing through the fiber cartridges which have just :been saturated with gasolene will become highly volatilized and will pass from the lower end of'the carbureting tube into the gasometerindicated a-t B", or may escape through the 'service'pipe 33' for direct use.

One of the important features of the pres entinverrtion issth'eprovision ofan auxiliary vaporizer; This iszinterposedbetween the outlet of the carbureting' tube 13'and the gasometer Bandall' the gas previously pro duced" in the carb'ureting tube is further acted on by being :passed through" the auxil iary carbureter indicated at C. Thiscar= b'ureter consists of three or more tubes 34,

35iand36', interior'ofwhich' aremounted a' plurality of" fiber" cartridges such as indicated in Figs. 4: and 5.

Mounted on the lowerpipe 36"oftheauxiliary carbureter is an inletvalve '37 and a check-valve 38. All air admitted to the carbureter on the. upward movement ofthe bell enters through valve37 then passes through the several fiber cartridges'mounted'in'tubes' 35 and 34 and thecartridge's mounted in the carbureting tube '13." The air is thus partly volatilized Ion the suction or'inta-ke stroke of the bell, but "the complete volatilization takes place on the downward movement of the'bell as the several fibercartridges are'thoroughl'y saturatedwith gasolene just previous-to the downward movement of the bell. The air will pass through the cartridges 15 in the carbureting tube and then through the cartridges in the tubes 31, 35 and 36 and is finally permittedto enter the gasometer B or fiow directly through the service pipe 33 for distribution.

The cartridges introduced into the tubes 34, 35 and 36 are preferably cylindrical in orosssection, asindicated in Fig. 4, and are constructed in lengths suitable for various installations. These tubes are constructed of wire fabric and a fibrous string, such as cotton or hemp, is then threaded through same, as indicated in Fig. at. The gasolene coming from the carbureting tube and draining into tubes 34, 3'5 and 36 will thus be absorbed by the fiber of the auxiliary vaporizing cartridges. The action of capillaryattraction will cause the gasolene to be com-- pletely absorbed by the fibrous strings of-the several cartridges'and it is here presented to the volume of moving air in the highly attenuated form whereit'will be quickly absorbed. Dry carbureted air is'thus quickly produced by the useof 'a very simpleapparatus which may be operated with a minimum amount of power from such sources asstorage water tanks, andthe like.

Tube 2% is preferably loaded with mercury sothat'the arm, when once moved a'little beyond the horizontal in either direction,

willquickly drop to one side-or the other to 1 along to the gasometer and also to the burners on the service pipe: As soon' as-the bell of""carbureter A reversesor moves up on its'suction'stroke, the pressure will cease and the'burners or lights will become extinguished. This is, however, preventedby the closing of checkvalv'e 38 and the surplus supply of carbjureted' air carried by the gasometer; Without the'least fluctuation in the lights or burners. The ebb from thegasomete'r sets in instantly and suppliesthe' service pipe. Weights are placed in the two bells to'regulate the 1 carbureted" air pressure and to keep them in balance with" each other:

A machine-const1'ucted as-h'ere shown per mits the generation of' carbureted air of- Knowing 7 thecubic'contents ofthe carbureting bell, it isfixed and uniform quality.

possible to adjust the cup '8' to'd'ip' and empty just the right'quantity' 'of gasolene to saturate that "much air to'make the carbureted air just the richness desired. When so adjusted, carbureted' air of 1 absolute uniform standard"richness, independent ofheat orcold, wet or dry, is secured. The richness of the carbureted air'may be changed at any While the This action is" instantaneous time by adjusting the dip of the cup. The machine will thus generate the desired mixture continuously until again adjusted by the operator.

The auxiliary carbureter is an extension of the carbureting tube, and the interior of same is provided with the same fuzzy strings for the purpose of distributing, by capillary attraction, the gasolene in extremely attenuated form to the moving volume of air. All the gasolene that trickles through the carbureting tube creeps along in the trough of the auxiliary tube and climbs up the flax threads when it is swept of? as vapor by the passing current of air. The lower auxiliary tube is provided with a grease trap 36 in which the greasy residue of the gasolene is collected.

A pet cock 36 is provided at the bottom of the trap so as to permit the removal from time to time of the collected residue. The provision of the trap keeps the carbureter clean and also prevents the service pipe from becoming choked.

I wish it understood that various other modifications may be made within the scope of the appended claims and that I do not wish to limit myself to the specific design and construction here shown.

The materlals and finish of the several parts of the carbureter are such as the experience and judgment of the manufacturer may dictate.

Having thus described my invention, what I claimand desire to secure by Letters Patent is 1. In a carbureter having a carbureting chamber, a cartridge in the chamber come posed of a pair of substantially parallel spaced rings connected by spaced cross rods, and fabric strings stretched across the rings and across the space between the rings and rods so as to form a drum defined in outline by a network of strings.

2. In a carbureter, a cartridge composed of a pair of substantially parallel spaced rings, cross rods connecting the rings and having their ends extending beyond the respective rings, and fabric strings stretched across the rings and transversely across the space between the rings and around said rod ends so as to form a drum defined at its top, bottom, and periphery by a network of strings.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
